Religionless Christianity

Religionless Christianity () is a theological concept developed by Dietrich Bonhoeffer in letters written from Tegel Prison in Berlin during the final year of his life, 1944. The phrase appears in Bonhoeffer's correspondence with his friend and former student Eberhard Bethge, later published as Letters and Papers from Prison. In these letters, Bonhoeffer questioned whether Christianity could and should be expressed without the trappings of "religion," which he associated with metaphysics, inwardness, and the use of God as a solution to problems that human beings could not yet solve on their own.

Because Bonhoeffer was executed by the [...] on April 9, 1945, he was unable to develop these IDeaS into a systematic treatment. The concept consequently remains fragmentary, consisting primarily of a series of letters written between April and August 1944 and an outline for an unfinished book whose manuscript was lost. The resulting ambiguity has made religionless Christianity one of the most debated concepts in twentieth-century theology, with interpreters ranging from death of God theologians to conservative evangelicals claiming Bonhoeffer's legacy.

Background and context

Bonhoeffer wrote the theological letters from Tegel Prison, where he had been held since April 1943 on charges related to his involvement in the resistance against the [...] regime. He was simultaneously implicated in the 20 July plot to [...] Adolf Hitler. The letters were written to Bethge, who had been a close associate since the mid-1930s and who later edited and published them posthumously.

The concept did not emerge without precedent in Bonhoeffer's earlier work. His 1937 book The Cost of Discipleship had criticized "cheap grace," the reduction of Christianity to a set of doctrinal assurances without the cost of following Christ. Life Together (1939) described the practices of the underground seminary at Finkenwalde. In his unfinished Ethics (written 1940–1943), Bonhoeffer developed the idea that the reality of God and the reality of the world are not two separate spheres but are held together in Christ. Scholars such as Eberhard Bethge and Peter Hooton have argued that religionless Christianity should be understood as a continuation and culmination of these earlier themes rather than a radical break from them.

The letter of April 30, 1944

The phrase "religionless Christianity" appears for the first time in a letter dated April 30, 1944:

In subsequent letters, Bonhoeffer developed several interrelated ideas.

Critique of "religion"

For Bonhoeffer, "religion" did not mean faith or Christianity as such but rather a particular way of being Christian that he regarded as distorted. He identified several features of this "religion" that he wished to move beyond.

First, religion treated God as a metaphysical hypothesis, a being "out there" or "up there" whose existence could be debated philosophically. Second, religion was characterized by inwardness: a focus on the private, interior life of the soul at the expense of engagement with the world. Third, religion operated as a deus ex machina, invoking God primarily at the boundaries of human knowledge and capacity, so that as human knowledge expanded, God was pushed to the margins. Bonhoeffer objected that this made God a "stopgap" for the incompleteness of human understanding.

"A world come of age"

Central to Bonhoeffer's thinking was the claim that the Western world had "come of age" (). By this he meant not that humanity had become morally mature but that it had learned to manage its affairs, in science, politics, ethics, and daily life, without recourse to the "working hypothesis" of God. Bonhoeffer traced this development from the thirteenth century onward and regarded it not as a tragedy but as a legitimate achievement that Christians should welcome rather than resist.

He was sharply critical of Christian apologetics that tried to push people back into a posture of dependence on God by exploiting their weaknesses, anxieties, or the limits of current knowledge. He called this approach "pointless, ignoble, and unchristian": pointless because it tried to reverse an irreversible historical development; ignoble because it exploited weakness; and unchristian because it confused Christ with a particular stage of human religiosity.

Being for others

In place of the "religious" God invoked at the boundaries of life, Bonhoeffer pointed to the God found at the center of life. In an outline for a book that he sketched in August 1944, he wrote that the experience of transcendence is the experience of "being there for others," and that the church is "the church only when it exists for others."

This idea built on Bonhoeffer's earlier Christology. In his 1933 Berlin lectures on Christology, he had asked "Who is Jesus Christ for us today?" rather than "What is the nature of Christ?" The prison letters extended this approach: Christ is not the answer to metaphysical questions but the one who exemplifies and enables authentic human existence oriented toward others. As Bonhoeffer wrote: "The Christian is not a homo religiosus, but simply a man, as Jesus was a man."

Secret discipline

Bonhoeffer did not propose abandoning Christian worship, prayer, or the sacraments. He referred to what he called the disciplina arcani (secret discipline), the early church practice of reserving certain rites and teachings for baptized members. Prayer, worship, and the inner life of the Christian community would continue, but they would not serve as the public face of Christianity in a world come of age. The public expression of faith would instead take the form of engagement with the world: prayer and "righteous action among men."

The unfinished book

In August 1944, Bonhoeffer sent Bethge an outline for a book he intended to write, divided into three chapters: an assessment of the current situation of Christianity, the meaning of the concepts of the faith (God, Christ, the church, life, death, etc.) reinterpreted in light of a world come of age, and a sketch of what a religionless Christianity would look like in practice. The manuscript was lost when Bonhoeffer was transferred from Tegel to other prisons before his execution. Only the outline and some notes survive.

Interpretive debates

The fragmentary nature of Bonhoeffer's prison theology has generated a sustained debate about what he intended and how his ideas should be developed.

Continuity versus discontinuity

A central question in Bonhoeffer scholarship is whether the prison letters represent a break from his earlier theology or a continuation of it. Bethge, who knew Bonhoeffer better than anyone, argued in his biography that there was significant continuity, describing the prison theology under the heading "The New Theology" but emphasizing that the roots lay in Bonhoeffer's earlier work. Hooton has argued at length that religionless Christianity is best understood as emerging naturally from Bonhoeffer's lifelong Christological focus and his earlier critique of religion in works such as Sanctorum Communio and the Berlin Christology lectures.

Other interpreters have seen a more dramatic shift. Karl Barth, reading Letters and Papers from Prison after their publication in the early 1950s, expressed puzzlement at what he perceived as a change in Bonhoeffer's direction.

Radical appropriations

In the 1960s, the death of God theologians, particularly Thomas J. J. Altizer, claimed Bonhoeffer as a forerunner. Bishop John A. T. Robinson's Honest to God (1963) drew extensively on Bonhoeffer alongside Paul Tillich and Rudolf Bultmann to argue for a Christianity freed from traditional theism, and brought Bonhoeffer's prison ideas to a wide popular audience.

Paul Lehmann, a friend of Bonhoeffer's, warned against these appropriations, arguing that "both cultic and atheistic celebrations of Bonhoeffer are grievous distortions of his thought and spirit" and that the prison letters must be read alongside Bonhoeffer's earlier exegetical and theological writings.

Conservative readings

Evangelical and orthodox interpreters have argued that Bonhoeffer's critique of "religion" was directed at cultural Christianity and institutional complacency, not at Christian doctrine or supernatural belief as such. On this reading, religionless Christianity is a call for more authentic, costly discipleship in continuity with The Cost of Discipleship, not a proto-secular theology. The Themelios article by the Gospel Coalition argues that Bonhoeffer's ecclesiology, developed in Sanctorum Communio, provides the key to understanding religionless Christianity: he contrasted the genuine church community ("Christ existing as church-community") with religion as a merely human phenomenon driven by natural impulses rather than divine revelation.

Legacy

Bonhoeffer's prison reflections have influenced a range of subsequent theological developments. Robinson's Honest to God drew directly on the prison letters, and the death of God theology of the 1960s claimed Bonhoeffer as a forerunner. Hooton's 2022 monograph treats religionless Christianity not as a "fragment or historical artifact" but as "a fully functional theology" with ongoing relevance.
